Homemade Plastic Tool To Shove Insulation Into Concrete Expansion Joints
Using his hand-held grinder with a metal cutting disk, Prose cut a 1/4-in. wide slot about 1 in. deep into the end of a piece of 3/4-in. dia. copper tubing. Then he mounted a 1 1/2-in. dia. washer in the slot, securing it with a 1-in. long sheet metal screw.
“The washer easily rotates when I push the insulation 3/4 of an inch into the expansion joints. The screw that holds the washer in place guides the insulation to the exact depth needed all along the joints. Once the insulation is in place, I caulk all the joints, let the caulk dry, then scrape the surface smooth to create a seam that won’t collect dirt or gravel in my new shop floor. It couldn’t have worked any better if an engineer had designed it on CAD.”
